如何作为迁移的一部分播种特定 table - Laravel 5？

Question

我有这个命令

php artisan db:seed --class=GraphsTableSeeder

我需要在我的部分代码（迁移）中运行。

我该怎么做？

<?php

use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;

use App\Models\Graph;


class RescueGraphsTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        if (Schema::hasTable('graphs')) {

            $graphRecords = Graph::all();

            if(count($graphRecords) == 42){
                echo "graphs table has good data.";
            }

            //truncate
            DB::table('graphs')->truncate();

            //add data
            //php artisan db:seed --class=GraphsTableSeeder ✨

        } else {

            //add graphs table

            //add data
            //php artisan db:seed --class=GraphsTableSeeder ✨

        }
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        //
    }
}

我有点卡住了，请帮忙。

    /**
     * Run the migrations.

    public function up()
    {
        if (Schema::hasTable('graphs')) {

            if(Graph::count() == 42){
                echo "graphs table has good data.";
            }

            DB::table('graphs')->truncate();

        }

        $exitCode = \Artisan::call('db:seed', [
            '--class' => 'GraphsTableSeeder'
        ]);
    }

    /**
     * Reverse the migrations.

     * @return void
     */
    public function down()
    {
        //
    }
